Researchers created an innovative, built-in device for aligning below-knee prostheses. This cost-effective solution offers independent, stepless adjustments for angle and slide, simplifying prosthetic fitting and socket replacement.

Area of Science:

  • Biomedical Engineering
  • Prosthetics and Orthotics

Background:

  • Traditional below-knee prosthesis alignment can be complex and time-consuming.
  • Existing alignment devices may lack independent adjustment capabilities or require extensive modification after prosthetic manufacture.

Purpose of the Study:

  • To develop and present a novel, integrated device for the alignment of below-knee prostheses.
  • To offer a solution that allows for independent, stepless adjustment of angle and slide post-prosthetic manufacture.

Main Methods:

  • The device integrates a half-sphere for angle adjustment and a plate for slide adjustment and socket attachment.
  • The design allows for re-use of the main device components when the prosthetic socket needs replacement.

Main Results:

  • The developed device provides one-point, stepless adjustment of both angle and slide, independently.
  • The alignment device is characterized by its light weight, compact size, cosmetic concealability, and low cost.
  • The design facilitates easier socket exchange, enhancing practicality.

Conclusions:

  • The new in-built alignment device offers significant advantages over existing designs due to its simplicity and integrated functionality.
  • This innovation streamlines the alignment and socket exchange process for below-knee prosthetics, potentially improving patient outcomes and prosthetic care.
